Objectives: Aripiprazole is an antipsychotic that functions as a partial agonist in hypodopaminergic states and a dopamine antagonist in hyperdopaminergic states. Methods: This paper reports a series of five clinical cases of worsening psychotic symptoms in schizophrenic patients related to the initiation of aripiprazole, oral and injection, as combination therapy. Results: In all five cases, the switching of aripiprazole improved the psychotic symptoms. Conclusion Even with the suggestive relationship between aripiprazole therapy and the worsening of psychotic symptoms, further research is needed.

Insulinoma is rare functioning islet cell tumor of pancreas and its main feature is frequent attacks of hypoglycemia. Because of frequent seizure, the disease is occasionally mistook as epilepy. We experienced a case of insulinoma with dilantin toxicity in a 45 year old patient who had been treated with dilantin for 7 years. Selective splenic arteriogram showed 0.8cm mass in the tail of pancreas which was proven insulin secreting tumor on histiopathological examination. After operation no more seizure attack was detected and her blood sugar level was well maintained within normal range. This case might provide an insight that the possibility of insulinoma should be considered in patient with episodic neurobehavioral dysfunction such as epilepsy.

The levels of tartrate resistant acid phosphatase (TRAP), matrix metalloproteinase-2 (MMP-2), and tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) in synovial fluid (SF) and serum in cases of canine osteoarthritis (OA) were measured. OA was induced by a surgically-created medial patellar luxation in the left stifle of 24 dogs. SF and blood samples were collected at 1.5- and 3-month intervals, respectively. Every 3 months, one dog was euthanatized to collect tissue samples from both stifles. TRAP levels in SF and serum were measured using a spectrophotometer, and TRAP-positive cells in joint tissues were identified by enzyme histochemistry. MMP-2 and TIMP-2 in SF and serum were detected by Western blotting and ELISA, respectively. TRAP in SF from the stifles and serum was significantly increased (p < 0.05) after 3 months. TIMP-2 in SF and serum was significantly decreased (p < 0.05), whereas MMP-2 in SF was significantly increased (p < 0.05) during the progression of OA. Histochemistry revealed an increased number of TRAP-positive cells in tissues from OA-affected joints. Assays measuring TRAP, MMP-2, and TIMP-2 in SF and serum, and methods that detect increased numbers of TRAP-positive cells in the joint tissues can play an important role in identifying the early phases of degenerative changes in canine joint components.

OBJECTIVES: The aim of this study was to evaluate the psychopathological features such as depression and anxiety in schizophrenics with obsessive-compulsive symptoms (OCS) as well as the severity of OCS according to duration of schizophrenia. METHODS: We randomly selected sixty four inpatients with schizophrenia. We classified the patients into two groups (OCS group, non-OCS group) according to the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Clinical and demographic features were evaluated. To assess OCS, Y-BOCS were performed. The Korean version of the Positive and Negative Syndrome Scale(K-PANSS), the Brief Psychiatric Rating Scale (BPRS), the Korean version of the Calgary Depression Scale for Schizophrenia (K-CDSS), the Beck Anxiety Inventory (BAI) and the Satisfaction With Life Scale (SWLS) were conducted. Independent t-test and chi-square test were conducted to compare the two groups. Pearson correlation analysis was performed to examine the relationship between the duration of schizophrenia and the Y-BOCS score. RESULTS: The Y-BOCS, K-CDSS, and BAI scores were higher in the OCS group. There was a significant correlation between the duration of schizophrenia and the Y-BOCS score. CONCLUSIONS: Anxiety and depression symptoms were severe in the OCS group. In addition, the results of this study indicate that the longer duration of schizophrenia, the more severe the OCS. Therefore, the evaluation of OCS in schizophrenics should be accompanied by treatment intervention.

To induce bone formation at ectopic site by tissue engineering and gene therapy, we transplanted collagen sponges containing rhBMP-7 transduced HEK 293 cells in the hypodermis of nude mice. Bone formation was investigated by histological and electron microscopic method at 3, 6, and 9 weeks after transplantation. At 9 weeks after transplantation, eosinophilic bony tissue was observed in the implanted collagen sponge and was confirmed as bone tissue by Von Kossa stain. In the transmission electron microscopic observation, the cells in newly formed bone tissue had eccentrically located nucleus and well developed rough endoplasmic reticulum (rER). Therefore, the cells were evaluated as osteoblasts. Those results suggest that it is possible to form a bone tissue in the ectopic site by transplantation of rhBMP-7 transduced HEK 293 cells. This will be contributed to push more advanced gene therapy for bone formation. However, the HEK 293 cell is unable to apply to the clinical gene therapy. Therefore it is worth to find more compatible cells for clinical application. In addition, collagen sponge is considered as an excellent scaffold and/or carrier for gene therapy and a good biomaterial for tissue engineering.

Idiopathic ketotic hypoglycemia (IKH) is the common cause of clinically significant non-diabetic hypoglycemia among children. The cause of IKH is decrease in endogenous glucose production after a prolonged fasting. We report the experience of perioperative management for a six-year-old female child undergoing strabismus surgery with a history of IKH. This patient experienced two episodes of severe hypoglycemia and loss of consciousness caused by prolonged fasting at the age of 31 and 41 months. For elective general anesthesia, children should be restricted from fluid and foods to prevent pulmonary aspiration. Because of higher metabolic rate and larger body surface area-to-weight ratio than adult, pediatric patient are more prone to hypovolemia and hypoglycemia during preoperative fasting period. When the preoperative fasting is inevitable in the child with IKH, anesthesiologist should start the parenteral infusion with dextrose-containing fluid and periodically check blood glucose level during perioperative period.

We report a successful pregnancy in a woman who at the age of 31years received chemotherapy for mucinous cystadenocarcinoma of the right ovary. She was treated with multiple chemotherapy including cis-platinum, cyclophosphamide, adriamycin, and oral melphalan. She had microscopic residual cancer at the opposite ovary at second-look laparotomy. She developed secondary amenorrhea with symptoms of menopause after commencing treatment which persisted on its completion. Biochemical investigations were consistent with ovarian failure, which was assumed to be chemotherapy-induced. She was given hormonal replacement therapy with a conjugated equine estrogen/medroxyprogesterone acetate combination, resulting in regular withdrawal bleeding. The patient conceived 5 years after completing chemotherapy and gave birth a normal infant at term.

OBJECTIVE: To assess the influence of reflex sympathetic dystrophy (RSD) on functional status and recovery of the hemiplegic upper extremity in stroke patients. METHOD: Retrospective chart review was performed in 561 patients. Among 561 stroke patients, 116 subjects were recruited and classified into two groups: patient group, 43 cases with RSD; control group, 73 cases without RSD. Upper extremity function was assessed based on feeding, dressing and personal hygiene scores of the modified Barthel index at the beginning of rehabilitation treatment and at the time of discharge. Causes of stroke and length of stay were recorded. Median nerve-somatosensory evoked potential studies were performed and assessed. RESULTS: The incidence of RSD was 7.7% and the time to development of RSD was 62.3+/-34.1 days after the onset of stroke. There was no significant difference in functional status between two groups at initial and final evaluation. The upper extremity function had improved in both groups although the length of stay was longer in patient group. SSEP abnormalities were more frequent in the patient group. CONCLUSION: The presence of well-managed RSD affected neither the functional status nor the functional recovery of upper extremity in stroke patients.
